Some great stuff on here today! Never having been a huge Beatles fan, I do enjoy their music, and that's a pretty good song. I like the take on the second one, of course they couldn't outdo Charlie Daniels, who could?
That last one was impressive, that girl has one hell of a voice. While they didn't do anything original with it she really had the energy of the original. I would go with the third today as my pick, it's always fun to hear some new takes on old songs!
